IMPROVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 202,192, dated April 9,1878; application filed December 27, 1877.

To all whom it may concern:

Be it known thatI, JOHN B. REED, of Westfield, State of Massachusetts,have invented Improvements in Steam-Radiators, for warming buildings;and I hereby declare that the following is a full, clear, and exactdescription and specification of the same, taken in connection with theaccompanying drawings, making part thereof.

My invention appertains to radiators made with circulating-divisions,connected by joints to a base provided with induction and eductionopenings, so that steam from a boiler may enter, circulatethrough thedivisions, and condense, the heat thus set free being radiated into thesurrounding air through their exterior surfaces.

My invention consists in certain new combinations of mechanism,specifically set forth at the end of this schedule, by means of which Iam able to produce steam-radiators more durable, more cheaplyconstructed, and less liable to leak than those now in use.

In order that persons skilled in the art may understand, make, and usemy improvements, I will proceed to describe, by aid of the drawings, themanner in which I have embodied them.

Figure 1 represents a vertical end view of said radiator complete. Fig.2 represents a vertical side view of same, partly in section. Fig. 3represents a top view of said radiator, having threecirculating-divisions alike, the center one being shown in section on ahorizontal line, w 00, Fig. 2. Fig. 4 is an enlarged vertical sectionthrough the center of one of the legs of the circulating-divisions,showing the new means of connection between the legs and thereservoir-base.

A is the reservoir-base, mounted on feet a a. It is hollow, and isprovided with inlet and outlet openings 12 1). Its upper face isperforated by six openings, 0 0, communicating with the interior of saidreservoir. It is also provided with the inner walls a a, surrounding theopening 01, which extends entirely through from the top to the bottom,leaving the interior steam-space inone continuous channel.

B B B are the circulating-divisions, the legs f f of each beingconnected at the top by a horizontal pipe, 0, forming one piece. Theyare hollow, to permit a continuous circulation or flow of steam throughthem. These legs are partially closed at the bottom, but tubes 9 extendfrom it downward, tapered on their exterior surfaces, their diameterbeinggreatest near the bottom of the legs, where the legs and the tubeare united. Through these tubes the steam flows to and from thereservoirbase. The holes 0 o in the reservoir-base are made larger thanthe outer diameter of the said tubes, and are provided with shoulders KK, forming ring-shaped recesses, into which are placed soft-metal rings1 1, large enough in diameter to nearly fill the recess, but with aninternal diameter smaller than the exterior diameter of theupperportions of the tubes 9 before they are put into the rings and the ringsinto the recesses.

The holes 0 o in the base A may be cast on chills, and the tubes 9 arecast in chills, so that their tapering surfaces are hard and smooth.This latter is an important feature of my radiator.

The rings of soft metal having been placed in the holes 0 0, the ends ofthe tubes on the divisions B are inserted in the rings, and the wholeplaced under a powerful press, when the tubes are forced into the ringsuntil the bottom of the divisions B are in contact with the upper partof the base A, or nearly so. The taper of the tubes spreads the ringsinto the recesses, makes a tight fit between the tubes and the rings, aswell as between the rings and the recesses, and renders the joints firmand steam-tight.

The holes I) b are tapped out to receive the steam-pipes, and a bolt, m,is put through the several divisions, as shown, to hold them together.

A bolt, a, and a bar, p, are shown holding the center division tothereservoir-base. They are not necessary under ordinary circumstances,but may be useful to guard against the accidental loosening of thejoints by severe blows.

The operation of the radiator is as follows: Steam is admitted through apipe screwed in opening b into the interior of the reservoirbase A. Itthen flows up the legs of the circulating-divisions B B B on one side orthe other, and down the legs on the other side condensing partially, asit flows forward, the water of condensation with any uncondensed 'steam;then flows out from the pipe in the hole b on the side opposite theinlet-pipe b. p

The heat given 011' by the condensation is thrown into the airsurrounding the radiator, as is well understood.

I do not claim, broadly, the method of uniting two parts by forcingtubes into rings held in recesses to make tight joints, as shown in W.Smiths patent of September 15, 187 4, or in E. G. Blakeslees patent ofJuly 16, 1867, each for improved clamps and couplings.

Having now fully described my invention in the form in which it wasembodied by me, what I claim, and desire to secure by Letters Patent,is-

1. The combination, substantially as hereinbefore set forth, in asteam-radiator, of the reservoir-base, provided with recessed holes inits upper plate, and double-legged circulate ing-divisions, cast inonepiece, having taper ing end tubes, with soft-metal packing-rings toseal the joints, all constructed and arranged to operate substantiallyin the manner described.
